Choosing an international school in Brussels is one of the first big decisions expat families face when they arrive in the capital of Europe. With a large diplomatic community, EU institutions and multinational headquarters, Brussels has one of the densest concentrations of international schools anywhere in Europe, and the choice can feel overwhelming. This 2026 guide walks you through the curricula on offer, the leading schools, realistic fee ranges and the practical steps that make an admission run smoothly.
International curricula available in Brussels
Brussels caters to almost every major educational pathway, which is exactly why so many globally mobile families settle here without worrying about continuity for their children.
- International Baccalaureate (IB): Several schools offer the full continuum from the Primary Years Programme through to the Diploma Programme, ideal for families who expect to move again.
- British curriculum: IGCSE and A-Levels are widely available and popular with families heading toward UK universities.
- American curriculum: US-style programmes with Advanced Placement suit families on shorter postings or planning a return to North America.
- French and bilingual tracks: Given Belgium's francophone context, many schools run strong French-English bilingual programmes.

International school fees in Brussels
Fees vary widely depending on curriculum, age and whether meals and transport are included. As a realistic 2026 guide, expect the following annual tuition ranges:
- Early years / kindergarten: €12,000 to €22,000
- Primary: €18,000 to €28,000
- Secondary / IB Diploma years: €25,000 to €35,000+
On top of tuition, budget for one-off registration and enrolment fees (often €1,500 to €4,000), a refundable deposit, and extras such as lunches, school bus and uniforms. Many families whose employer offers an education allowance find that Brussels fees sit at the mid-to-upper end of continental Europe, though still below London or Geneva.
Practical tips for choosing and applying
Start early. The most sought-after schools in Waterloo and the eastern communes fill their places well before the September intake, and some maintain waiting lists for popular year groups. A few practical pointers:
- Match the curriculum to your next move, not just your current one. If another posting is likely, the IB continuum protects continuity.
- Think about commute. Brussels traffic is heavy; a school 15 km away can mean an hour each way. Check the school bus network before committing.
- Visit in person if you can. A campus tour tells you more about pastoral care and atmosphere than any brochure.
- Prepare documents in advance: passports, previous school reports, and any reference letters speed up the process.
